Detect if another script is online -TCP- ?

Recommended Posts


hi all

how can i detect if another script is online ?

i tried this :


sender code:

$TCPcon = TCPConnect (@IPAddress1, 1234)
While 1
TCPSend($TCPcon, "hi")

receiver code: 

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

GUICreate("Form1", 100, 222)
$Mainlist = GUICtrlCreateList("", -1,-1, 615, 227)

$TCPlisten = TCPListen(@IPAddress1, 1234)
$TCPaccept = TCPAccept($TCPlisten)

While 1
$GUImsg = GUIGetMsg()
If $GUImsg = $GUI_EVENT_CLOSE Then Exit
$TCPRecv = TCPRecv($TCPaccept, 99999999)
$TCPaccept = TCPAccept($TCPlisten)
Until $TCPaccept <> -1

GUICtrlSetData($Mainlist , "")
Until $TCPRecv <> ""
GUICtrlSetData($Mainlist , $TCPRecv)

in receiver code: 

i cant understand what is happening when i use "DO" inside "While loop" and why tcp accept and tcp receive will not work when i remove the DO although there is while that supposed to make it always running

and why the close button is not closing the script

in sender code:

i know that i'm doing the connection wrong i must not use while

but i'm confused what i must use to tell the other side that i'm connected so im listed in his list ?


please help me this is the first time i use tcp
